I always liked the company logo for the guy that made the Jojo’s Bizarre Adventure manga:

The little callous on the finger is what artists get from holding a pencil so much. Something like that to designate physical work would be cool.

I like that this approach identifies what the product is, instead of what it isn't.

iHeartRadio uses the sound of a heartbeat plus the phrase "Guaranteed human" at the start and end of a bunch of their podcasts. I know what they mean, but I do wonder if the majority of listeners will understand that they mean "No AI."

I'm imagining the Fallout guy with a big thumbs up

Perfect. This way too when someone tries to pass off an AI image prompted to incorporate the “not AI” symbol we’ll know it’s a fake because of the excessive amount of fingers in the anti-AI logo.

Ironically, GenAI had such a time with hands. What a better symbol to represent authenticity.

Agreed. It also nicely plays into the idea of manual labour, 'manual' literally meaning 'by hand'.

Literally allows up to 10% to be AI generated. Charging a fee for commercial use, but I can't see what that fee is. Feels like a psyop.
